"It's all a mystery," he said. "Is the vehicle down by the border a ploy? Were they voluntarily missing? Were they taken against their will? ... Just for a family of four to disappear, I've never seen anything like it."

The Eufaula family was looking to buy 40 acres of land near Red Oak when they promptly disappeared. Their abandoned truck was found by hunters last weekend, but this doesn't look like a case where they vanished on their own accord. Their dog was found in the truck malnourished after days of going without food or water. Police also discovered their IDs, wallets and a substantial amount of cash.
